When you download Windows from Microsoft Store or any online source, you download it as an ISO file. An ISO file combines all the Windows installation files into a single uncompressed file – like a DVD clone or backup. With ISO file so you can create (burn) a bootable DVD or USB drive containing Windows installation files.

This allows you to install new Windows OS onto your PC. If you change the boot order of drives in your PC’s BIOS, you can run the Windows installation directly from your DVD or USB drive when you first turn on your computer. You can search for information about how to change the boot order of drives in your PC BIOS.

Step 2 – Click on USB Device as media type you would like to use to create Windows 7 bootable USB drive.

Step 3 – From Drop Down box select your USB Pen drive letter, e.g., H: or I: or G: and then click Begin copying. After the process is completed the USB is now bootable. Turn off your computer and plug in USB. Now Turn on PC and boot from USB. Done.

When your Windows ISO file is copied, install Windows by moving to the root folder of your USB drive, and then double-click Setup.exe.

I went from win 7 pro 32 bit to win 7 pro 64 bit lastnight without the bootsect.exe and the download worked and 64bit is now installed. Will i run into any issues for not installing with bootsect.exe?! I used a product key my preinstalled machine came with.

Michell Tan

Hi there, I am also using windows xp and i wanted to upgrade to windows 7. Did you use the first method? The first method is quite complicated as there’s many thing to download and i tried and decided to stop and use a better method. There’s a second method, did you see?
If not, let me show you.

-Install the Rufus Software and Open it. It can be downloaded here.
-After you open it. Follow Below Steps:
-Plug in your Pen Drive into USB Flash Port.
-To make a Windows bootdisk (Windows XP/7) select NTFS as file system -from the drop down.
-Then click on the buttons that looks like a DVD drive, that one near to the checkbox that says “Create bootable disk using:”
-Choose the XP ISO file.
-Click Start, Done!

So if you never see it, look here. I am trying now so i am not sure whether it going to work but it is much more easier than the first method.

Ken Newland

And to continue on for what Michell has laid out, you will just need to go to the USB and simply click on Setup. The method explained above is the easiest way to go. I would also recommend doing the setup without getting any updates, as it seems to make things difficult. It is much easier to get the updates after initial install.

you can follow the tutorial to create bootable USB without Rufus software.

hi I need to install windows 7 on my system I took my harddrive out and put it in another computer and formatted it but i do not know how to load windows from my usb stick onto the system from start up

Ninjallux

Its pretty basic… You gotta enter your startup boot menu, which you will see a command for it once you turn on your pc. And then choose to boot through your USB stick. Once you have figured that, just do the self explanatory steps to installing windows. Hope this helps! :D

Sir i have already downloaded the windows 7 professional iso and windows 7 usb installer for booting…after i install the usb installer and browse the iso file of windows 7 and open it will response to invalid iso file…what shall i do sir

Okay, so, my aspire one 522 would not boot up. I ended up at a lifeless, black screen every time. I do not know how to do any of this kinda stuff but after reading all about it here, I decided to give it a shot …….. And it worked. Installed Windows 7 ultimate, and everything .. Ummmm .. err .. looked or seemed okay. YAY ! Now I see that there are zero programs installed, zero drivers, can not get to internet. Device manager is almost empty, but what it does show, is innaccurate. Now, I don’t know what to do. What is my next move ? Please help. Thank you !

george

hi i downloaded the windows 7 ,but on the boot tool ,it says file is not a iso image

Jon

Download an ISO file of Windows 7 again in the Internet.You will know if it is an ISO image because it has .ISO.

Khang Nguyen

Dude please tell me the steps to do after copying all the files because I miss my old windows 7 so much compare to this windows 10 crap

Jon

Use a bootable DVD/ USB that has an ISO file.You can download the installer in the Internet.Turn off your computer.Turn it on and wait for POST on screen.Press F2 or DEL to get into BIOS settings go to Boot menu.Prioritize DVD or USB drive.If you your installation media is DVD then prioritize DVD drive to boot first on DVD.If it is a USB drive you’re using to boot first then priortize USB.After this press F10 to save changes in the BIOS settings.Then wait until you see on the screen “Press any key to continue”then press any key on the keyboard to start loading the installer into the computer.Wait until it you see the Windows 7 logo and the word install below it.Click install to start loading the operating system into the hard drive.Choose custom installation to have a clean install of the operating system.Click next or continue.Wait you see Local Disk C: click local disk C: and below the options click format.Click next or continue.Wait for the installer to load everything in your system.Wait until installation is finished.After that computer will restart after installation is done.Press F2 or DEL to get into BIOS settings.Go to Boot menu.Prioritize hard drive to boost first next time you start your computer.Press F10 to save changes in the BIOS settings.That’s all I can help.Hope this will help.

Actually the x86 has nothing to do with the software. It refers to the architecture of the CPU starting back in the beginning of PCs with the 286, then the 386, and later hence the name x86.

Bela Kazakova
